Contribution

It provides a comprehensive analysis of how R-Parity violation affects key phenomenological bounds and unification scenarios in supersymmetric models.

Findings

Relaxed bounds on charged Higgs mass from B(b -> s gamma)

Impact on lightest neutral Higgs boson mass

Connection between neutrino mass and Yukawa unification

Abstract

We review some properties of Bilinear R-Parity Violating models: simple extensions of the Minimal Supersymmetric Standard Model motivated by spontaneous breaking of R-Parity. We concentrate on the relaxation of the bounds on the charged Higgs mass imposed by the measurement of B(b -> s gamma), the effect on the mass of the lightest neutral Higgs boson, the radiative breaking of the electroweak symmetry, the unification of bottom and tau Yukawa couplings, and the relation of these phenomena to the radiatively generated tau-neutrino mass.
